PR debug/98751 reports an issue in which most of libgccjit's tests
fails in DWARF 5 handling with
`.Ldebug_loc2' is already defined"
asm errors.
The bogus label is being emitted at the 3rd in-process iteration, at:
31673 ASM_OUTPUT_LABEL (asm_out_file, loc_section_label);
which on the initial iteration emits:
145 │ .Ldebug_loc0:
on the 2nd iteration:
145 │ .Ldebug_loc1:
and on the 3rd iteration:
145 │ .Ldebug_loc2:
which is a duplicate of a label emitted earlier:
138 │ .section .debug_loclists,"",@progbits
139 │ .long .Ldebug_loc3-.Ldebug_loc2
140 │ .Ldebug_loc2:
141 │ .value 0x5
142 │ .byte 0x8
143 │ .byte 0
144 │ .long 0
145 │ .Ldebug_loc2:
The issue seems to be that init_sections_and_labels creates the label
ASM_GENERATE_INTERNAL_LABEL (loc_section_label, DEBUG_LOC_SECTION_LABEL,
generation);
where "generation" is a static local to init_sections_and_labels that
increments, and thus eventually hits the duplicate value.
It appears that this value is intended to be either 0 or 1, but in
the libgccjit case the compilation code can be invoked an arbitrary
number of times in-process, and hence can eventually lead to a
label name collision.
This patch adds code to dwarf2out_c_finalize (called by
toplev::finalize in libgccjit) to reset the generation counts,
fixing the issue.

This patch removes a vestigial use of dk_no_check from
cp_parser_late_parsing_for_member, which ideally should have been
removed as part of the PR41437 patch that improved access checking
inside templates. This allows us to correctly reject f1 and f2 in
the testcase access34.C below (whereas before we'd only reject f3).
Additional testing revealed a new access issue when late-parsing a hidden
friend within a class template. In the testcase friend68.C below, we're
tripping over the checking assert from friend_accessible_p(f, S::j, S, S)
during lookup of j in x.j (for which type_dependent_object_expression_p
returns false, which is why we're doing the lookup at parse time). The
reason for the assert failure is that DECL_FRIENDLIST(S) contains f but
DECL_BEFRIENDING_CLASSES(f) is empty, and so friend_accessible_p (which
looks at DECL_BEFRIENDING_CLASSES) wants to return false, but is_friend
(which looks at DECL_FRIENDLIST) returns true.
For sake of symmetry one would expect that DECL_BEFRIENDING_CLASSES(f)
contains S, but add_friend avoids updating DECL_BEFRIENDING_CLASSES when
the class type (S in this case) is dependent, for some reason.
This patch works around this issue by making friend_accessible_p
consider the DECL_FRIEND_CONTEXT of the access scope. Thus we sidestep
the DECL_BEFRIENDING_CLASSES / DECL_FRIENDLIST asymmetry issue while
correctly validating the x.j access at parse time.
A earlier version of this patch checked friend_accessible_p instead of
protected_accessible_p in the DECL_FRIEND_CONTEXT hunk below, but this
had the side effect of making us accept the ill-formed testcase friend69.C
below (ill-formed because the hidden friend g is not actually a member
of A, so g doesn't have access to B's members despite B befriending A).

Since certain members of a class are a complete-class context
[class.mem.general]p7, we delay their parsing untile the whole class has
been parsed. For instance, NSDMIs and noexcept-specifiers. The order
in which we perform this delayed parsing matters; we were first parsing
NSDMIs and only they did we parse noexcept-specifiers. That turns out
to be wrong: since NSDMIs may use noexcept-specifiers, we must process
noexcept-specifiers first. Otherwise we'll ICE in code that doesn't
expect to see DEFERRED_PARSE.
This doesn't just shift the problem, noexcept-specifiers can use members
with a NSDMI just fine, and I've also tested a similar test with this
member function:
bool f() { return __has_nothrow_constructor (S<true>); }
and that compiled fine too.

memrefs_conflict_p assumes that:
[XB + XO, XB + XO + XS)
does not alias
[YB + YO, YB + YO + YS)
whenever:
[XO, XO + XS)

[YO, YO + YS)
In other words, the accesses can alias only if XB == YB at runtime.
However, this doesn't cope correctly with section anchors.
For example, if XB is an anchor symbol and YB is at offset
XO from the anchor, then:
[XB + XO, XB + XO + XS)
overlaps
[YB, YB + YS)
whatever the value of XO is. In other words, when doing the
alias check for two symbols whose local definitions are in
the same block, we should apply the known difference between
their block offsets to the intersection test above.

This is a follow-up fix to clean up pr91799. Per review of test results,

IPA-SRA already contains a check to figure out that an otherwise dead
parameter is actually required because of non-call exceptions, but it
is not present at the equivalent spot where SRA figures out whether
the return statement is used for anything useful. This patch adds
that condition there.
Unfortunately, even though this patch should be good enough for any
normal (I'd even say reasonable) use of the compiler, it hints that
when the user manually switches all sorts of DCE, IPA-SRA would
probably leave behind problematic statements manipulating what
originally were return values, just like it does for parameters (PR
93385). Fixing this properly might unfortunately be a separate issue
from the mentioned bug because the LHS of a call is changed during
call redirection and the caller often is not a clone. But I'll see
what I can do.

In dce6c58db8 msebor extended the
"malloc" attribute to support user-defined allocator/deallocator
pairs.
This patch extends the "malloc" checker within -fanalyzer to use
these attributes. It is based on an earlier patch:
'RFC: add "deallocated_by" attribute for use by analyzer'
https://gcc.gnu.org/pipermail/gcc-patches/2020-October/555544.html
which added a different attribute. The patch needed a lot of reworking
to support multiple deallocators per allocator.
My hope was that this would provide a minimal level of markup that would
support library-checking without requiring lots of further markup.
I attempted to use this to detect a memory leak within a Linux
driver (CVE-2019-19078), by adding the attribute to mark these fns:
extern struct urb *usb_alloc_urb(int iso_packets, gfp_t mem_flags);
extern void usb_free_urb(struct urb *urb);
where there is a leak of a "urb" on an error-handling path.
Unfortunately I ran into the problem that there are various other fns
that take "struct urb *" and the analyzer conservatively assumes that a
urb passed to them might or might not be freed and thus stops tracking
state for them.
Hence this will only detect issues for the simplest cases (without
adding another attribute).

As mentioned in the PR, since the switch to DWARF5 by default instead of
DWARF4, gcc fails to build when configured against recent binutils.
The problem is that cxx11-ios_failure* is built in separate steps,
-S compilation (with -g -O2) followed by some sed and followed by
-c -g -O2 -g0 assembly. When gcc is configured against recent binutils
and DWARF5 is the default, we emit .file 0 "..." directive on which the
assembler then fails (unless --gdwarf-5 is passed to it, but we don't want
that generally because on the other side older assemblers don't like -g*
passed to it when invoked on *.s file with compiler generated debug info.
I hope the bug will be fixed soon on the binutils side, but it would be nice
to have a workaround.
The following patch is one of the possibilities, another one is to do that
but add configure check for whether it is needed,
essentially
echo 'int main () { return 0; }' > conftest.c
${CXX} ${CXXFLAGS} -g -O2 -S conftest.c -o conftest.s
${CXX} ${CXXFLAGS} -g -O2 -g0 -c conftest.s -o conftest.o
and if the last command fails, we need that -gno-as-loc-support.
Or yet another option would be I think do a different check, whether
${CXX} ${CXXFLAGS} -g -O2 -S conftest.c -o conftest.s
${CXX} ${CXXFLAGS} -g -O2 -c conftest.s -o conftest.o
works and if yes, don't add the -g0 to cxx11-ios_failure*.s assembly.
